HEADLIGHT.

Application led August 3, 1925. Serial No. 47,759.

My invention relates to improvements in headlights.

rIhe object is to produce a headlight par-V ticularly intended for use on motor vehicles,

of attractive appearance and rigid, durable' both vertically and horizontally and held at adjusted angular positions.

An Object of importance is the provision in a headlight of the character, described of angularly-arranged guiding supports carried by the headlight casing and correspondingly angularly arranged supporting bands about the reflector, which bands are mounted within the guidesvin the casing to travel therethrough to support Vthe refiector for tilting movement.

Meritorious features consist in the employment of supporting mechanism adapted to hold the reiiector .at any position to which it has been adjusted without rattle and'to swing the reflector to adjusted' angular positions without play .of the parts lproducing undesirable noise.

Other important elements reside in the employment of' guides for the supporting bands, consisting of gurdmgvmembersdisposed on opposite sides of the reflector and held under spring tensionagainst the bands to prevent rattle vvof the moving parts as the bands travel through the guides together `with the employment ,ofA tension springs engaging the bands to hold the reflector atthe limit of its movement in one `direction as provided for by each band.

The above objects and important advantages together with others of considerable merit will more fully appear from the following specification, .appended claims and accompanying drawings, in which:

Figure 1 is aI front elevation fof my improved headlight.

fFig. 2 is a horizontal sectional View taken on line 2-2 of Fig. 1.

Fig.v 3 is a vertical sectional view taken on line 3-3 of Fig. 1.

Fig. l is a sectional view taken on line .l-fl of Fig. 3.

Fig. 5 is a perspective of the headlight from the rear with the casing broken away.

Fig. 6 is a perspective of one of the supporting guide brackets.

I provide a headlight having a rigidly supporting casing 10 within which is mounted a reflector 12. 4The casing is rovided with the usual headlight lens 1li hel in position in a manner well known andis supported by a hollow bracket 16 through which extends the electrical connection 18 that leads to the light bulb 2() removably mounted within a socket 22 carried by the reflector 12. This reflector is supported within the casing for tilting movement both horizontally and vertically and the connecting wire 18 is of such length as to permit this tilting movement. The reflector consists of a bowl-shaped member of .suitable material supported to permit of the swinging movement above described as follows:

The casing is provided with angularly arranged Vguiding supports. I have shown each guiding 'support as comprising two guide members positioned on opposite sides of the reflector in substantially the 'same plane, and each guiding member consists of va plurality of rollers 2li and 26. I have shown tworollers 2li carried-by a suitable .bracket .28 and a single roller 26 held by' springsBO to a seat -32 on the bracket 28 and guide member vThese bands cross each other and each bund is mounted in a guide for travel therethrough to support the reflector for swinging movement. It will be seen that the rollers 26 which are held by the springs y30 hold the bands 34 against the rollers 24.

The two bands just described which are disposed substantially at right angles to each other are pivoted to the refiector in substantially the same plane and so support the reflectoras to -permit of it'being tilted both in bands cross each other so as not to interfere.

with the movement of the bands and is fastened at the opposite end to a xed point such as i6 within the casing. This spring under normal conditions serves to hold the reflector to the full extent of its tilting movement in one direction, as in Fig. 2. The spring on the other band will, of course, hold the reflector to the full extent of its tilting movement as permitted by such other' band. rEhe springs, therefore, unless restrained, would hold the reflector tilted to the full extent of its vertical movement in one direction and to the full extent of its horizontal movement in one direction.

I provide means to actuate each band slidably through its supporting guide, which means may be of any suitable character and is here shown as comprising a flexible connection i8 connected with the reflector at 50 whereby the band may be moved aga-inst the tension of its spring 42 to the full extent of its movement in a direction counter the tension of the spring.

In Figs. 3 and 5 the reflector is shown in full lines at an intermediate position. In Fig. 2 the reflector is shown in full lines as held completely to one side by the spring 42 while the intermediate position of the reflector and its full swinging movementin the opposite direction is indicated in dotted lines.

What I claim is:

' l. In a headlight, a casing member, a reiiector member disposed'within the casing member, relatively angularly arranged bands secured to one member, correspondingly relatively angularly arrange-d guides carried by the other member, said bands mounted within said guides to travel therethrough in angular directions with respect to each other to permit tilting of the reflector within the casing in relatively angularly disposed directions.

2. In a headlight, a casing, angularly-arranged guides within the casing, a reflector, angularly-arranged bands about and pivoted to the reflector, said bands mounted within the guides to travel therethrough to support the reflector for swinging movement, and means operatively connected therewith to cause the bands to travel through the guides to tilt the reflector.

3. In a headlight, a casing provided with two guides one arranged substantially at right angles to the other, a reflector provided with two correspondingly arranged bands mounted for traveling movement withinthe guides, one band within one guide,

the other band within the other guide to support the reflector to swing as the bands are moved through the guides, each band being pivoted at its ends to the reector, and means operatively connected with the reflector to cause the bands to travel through the guides t-o swing the reflector.

4. In a headlight, a casing provided with angularly-arranged supporting guides, reflector in the casing provided with correspondingly-arranged supporting bands mounted within the guides to travel therethrough to support the reflector for swinging movement, each band pivoted to the reflector to permit it to swing therein, and L" means operatively connected Yith each band to move it through the guides to tilt the reflector within the casing.

5. In a headlight, a casing, av reflector within the casing, a light bulb within the reflector, a set or' guides within the casing disposed on opposite sides of the reflector in substantially the same plane, a second set ot' guides within the casing likewise disposed on opposite sides of the reflector in substantially the same plane and in a plane angularly disposedwith respect to the plane ot' the first set of guides, two bands about the reflector arranged angularly with respect to each other and pivoted to the reflector, one band mounted in one set of guides to travel therethrough, the other band niounted in the other set of guides to travel therethrough to support the reflector for swinging movement in the casing, and means operatively connected with the bands to more the same through the guides to swing the reflector therewith.
